EARTHQUAKE RESISTANT DESIGN OF STRUCTURESThis comprehensive and well-organized book presents the concepts and principles of earthquake resistant design of structures in an easy-to-read style. The use of these principles helps in the implementation of seismic design practice. The book adopts a step-by-step approach, starting from the fundamentals of structural dynamics to application of seismic codes in analysis and design of structures. The text also focusses on seismic evaluation and retrofitting of reinforced concrete and masonry buildings. The text has been enriched with a large number of diagrams and solved problems to reinforce the understanding of the concepts. Intended mainly as a text for undergraduate and postgraduate students of civil engineering, this text would also be of considerable benefit to practising engineers, architects, field engineers and teachers in the field of earthquake resistant design of structures. |

Popular passages
Page 14 - The earthquake is felt indoors by many people, outdoors by a few. Here and there people awake, but no one is frightened. The vibration is like that due to the passing of a heavily loaded truck. Windows, doors and dishes rattle. Floors and walls creak. Furniture begins to shake.
Page 15 - A suffer damage of grade 3, few of grade 4. In single instances land-slips of roadway on steep slopes; cracks in roads; seams of pipelines damaged; cracks in stone walls. c) Waves are formed on water, and water is made turbid by mud stirred up. Water levels in wells change, and the flow of springs changes.
Page 15 - VII Damage to buildings a) Most people are frightened and run outdoors. Many find it difficult to stand. The vibration is noticed by persons driving motor cars. Large bells ring. b) In many buildings of type C damage of grade 1 is caused; in many buildings of type B damage...
Page 15 - Unstable objects may be overturned or shifted. Open doors and windows are thrust open and slam back again. Liquids spill in small amounts from well-filled open containers. The sensation of vibration is like that due to a heavy object falling inside the building.
Page 16 - C suffer damage of grade 3, a few of grade 4. Many buildings of type B show damage of grade 4; a few of grade 5. Many buildings of type A suffer damage of grade 5. Monuments and columns fall. Considerable damage to reservoirs ; underground pipes partly broken. In individual cases railway lines are bent and roadways damaged.
Page 16 - Animals run to and fro in confusion and cry. b) Many buildings of Type C suffer damage of Grade 3, a few of Grade 4. Many buildings of Type B show damage of Grade 4, a few of Grade 5. Many buildings of Type A suffer damage of Grade 5. Monuments and columns fall. Considerable damage to reservoirs; underground pipes partly broken. In individual cases railway lines are bent and roadways damaged, c). On flat land overflow of water, sand and mud is often observed. Ground cracks to widths of up to 10 cm....
Page 16 - Loose ground slides from steep slopes. From river banks and steep coasts considerable landslides are possible. In coastal areas displacement of sand and mud ; change of water level in wells; water from canals, lakes, rivers etc. thrown on land. New lakes occur. XI...

Page 14 - The intensity of the vibration is below the limit of sensibility; the tremor is detected and recorded by seismographs only.
Page 59 - Disaster response alone is not sufficient, as it yields only temporary results at a very high cost. We have followed this limited approach for too long. This has been further demonstrated by the recent focus on response to complex emergencies which, although compelling, should not divert from pursuing a comprehensive approach. Prevention contributes to lasting improvement in safety and is essential to integrated disaster management.
